<strong>L</strong> = <span style="color:red">homline</span>(<strong>x1</strong>, <strong>y1</strong>, <strong>x2</strong>, <strong>y2</strong>) is a vector (3x1) which describes a line in
homogeneous form that contains the two Euclidean points (<strong>x1</strong>,<strong>y1</strong>) and (<strong>x2</strong>,<strong>y2</strong>).

</p>
<p>
Homogeneous points X (3x1) on the line must satisfy <strong>L</strong>'*X = 0.
